Two coherent sources 
and 
are separated by a distance four times the wavelength 
of the source. The sources lies along 
axis whereas a detector moves along 
axis. Leaving the origin and far off points the number of points where maxima are observed is

Here 
is the path difference 
for maximum intensity
Or 
Then 
Number of points for maxima becomes 3
